There are a number of ways to investigate the rate of a reaction in Chemistry. This is an outline of the required steps to undertake one of these methods. It is important in this core practical to use ...

The greater the frequency of successful collisions between reactant particles, the greater the reaction rate. Temperature, concentration, pressure and the use of catalysts affect reaction rate. Heat ...

Note: This demo has two parts, I & II. When ordering, please specify whether you want Part I, Part II, or both at the same time. I. The reaction between iodate and bisulfite in acid medium produces ...

where two ammonium ions and one bicarbonate ion are formed for each urea molecule that is hydrolysed. In addition, one proton is consumed which raises the pH. When calcium or other divalent cations ...
